PATENT OFFIQ FRED I. YOUNG, OF IAOINE, WISGOHSIR AIR DIRECTOR .VANE FOB UNIT HEATERS Application fled October 10, 1930. Serial No. 487,789.

' This invention relates to improvements in louver constructions for unit heaters of the class which are employed in the heating and ventilation of buildings. Due to the different '5 locations at which the heaters are most conveniently placed, it is desirable to provide the same with air directing means so that the air passing through the heater may be directed v outwardly at various angles such as downwardly, and partly to one side or straight ahead with deflection.

One of the principal objects of the invention is to provide in connection with a horizontal louver construction for eifectin the desired declination of air passing throug the radiator, a. vertical louver arranged cooperating with the horizontal louvers to be movable therewith in a vertical direction,

30 while having an independent lateral deflecting capacity.

A further object of the invention is to provide improved fixed louver constructions for directing air angularly with reference to the fore and aft axis of a heater.

The objects of the invention are accomplished by means of, constructions as illustrated in the drawings, in which:

Figure 1 is a fragmentary plan view of a unit heater provided with the improved louver construction.

Fig. 2 is a face view of the construction shown in Fig. 1.

Fig. 3 is a side view of the construction shown in Figures 1 and 2.

Fig. 4 is a fragmentary enlarged detail partly in section illustrating the method of attaching vertical vanes to horizontal vanes.

Fig. 5 is a face view of a modified form of the louver construction employing concentric deflectors, each flaring outwardly and having a common axis whichextends downwardly from the horizontal so that a conical column of air is delivered from the heater angularly with reference to the horizontal.

Fig. 6 is a side view of the construction shown in Fig. 5.

Fig. 7 is a face view of another modificae tion of the louver arrangement in which a plurality of continuous flaring vanes are empossiblysome lateral or vertical louvers which are either vertically or horico zontally arranged across the face of the heater and frequently hinged thereto so that the air may be deflected either downwardly or to one side of the direction in which the heater is facing.

The construction to which this application for patent relates is one in which the combined eifect of vertical and horizontal louvers may be had in one unit and in addition the louvers are arranged to direct the delivered currents of air outwardly in a flaring column so as to rapidly lessen the velocity and concentration of the heater air at a comparatively short distance from theheater. The purpose 7 is to provide for the delivery of a large quantity of heated air through a small unit while permitting the movement of the air to be not too apparent when the currents of air reach to within five or six feet from the floor.

The desired result may be obtained by any oneof the three forms illustratedbythe drawings. These forms in general are in one instance a set of parallel louvers hinged to the heater casing on friction pivots which serve to maintain desired angular relationship between the parallel louvers and the heater and supporting on the outer ends of these parallel louvers another set at right angles thereto but flaring outwardy with respect to each other. Alternative means for accomplish- 'ing the same purpose are illustrated in Sheet 2 of the drawings, and maybe continuous louvers such as the more or less conical circular ones shown in Fig. 5 or the rectangular. set shown in Fig. 7, each of which flare outwardly from the heater with respect to a com- 1 mon axis which may be declined or extend laterally from the horizontal.

Referring to the drawings, Figs. 1 to 4 illustrate one form of the louver construction as applied to the well-known type of unit heater, outlined in Figs. 2 and 3, and which in general comprises headers 1 and 2 for steam or hot water connected together by a radiator core, not shown, and the side plates 3. buch heaters are frequently suspended from ceiling beams and are therefore provided with the e es 4 on the upper header 1.

Air is blown t rough the heater by means of the motor driven fan 5 shown in Fig. 3, and the motor for which is indicated at 6. The motor is supported on bracket 7 extendin u wardly from the lower header 2. This unit eater is provided with the customary set of horizontally disposed air deflector vanes 8 pivoted to the side plates 3 of the heater on friction pivots 9.

The horizontal vanes or louvers 8 may therefore be set at different angles with respect to the horizontal. In order to provide for lateral deflection of the air with but slight change over the standard construction, at least two of the horizontal vanes are altered as illustrated by the detailed drawings, Figs. 4 and 1, to provide collared apertures 10, and recesses 11 at their outer edges for the purpose of supporting vertical vanes in fixed positions thereon without interfering wlth vertical adjustment of the horizontal vanes The vertical vanes effect lateral deflection of the air passing through the heater, and may be slightly curved in plan view as shown in Fig. 1, and in oppositely disposed sets so that the air will be directed outwardly on both sides in an enlarged column.

vertical vanes 13 are also cut out at 14 to clear the outer edges of the intermediate horizontal vanes 8. The projections 15 of the vertical vanes which are set within the apertures 10 of the horizontal vanes are formed to allow the necessary clearance upon adjustment of the horizontal vanes, and the recesses 11 are so located with reference to the apertures 10 to provide for permanent setting of the vertical vanes to suit the particular requirements in this regard for the intended use of anyone heater.

In the operation of the construction shown I in Figs. 1 to 4, inclusive, air blown through the heater may be directed in a generally horizontal direction, or upwardly or downwardly therefrom according to the adjustment of the horizontal vanes 8.

When adjusting these vanes with the vertical vanes mounted thereon, both horizontal and vertical vanes may be moved as a unit to a limited degree in a vertical direction. It is generally desirable to deflect the air downwardly by means of the horizontal vanes. The vertical vanes attached thereto serve the vanes 22. The common axis of these out-' wardly flaring vanes is'diagonal to the horizontal center line of a radiator. With this construction, the air which is blown through the radiator and heated thereby is spread conically as it leaves the radiator.

The rectangular arrangement of continuous vanes 23, shown in Figures 7 and 8, also serves to spread the air as it leaves the radiator uniformly at all sides from a common axis which extends downwardly from the center of the radiator.

Although s ecific embodiments of this invention have en illustrated and described, it is understood that modifications thereof may be made without departing from the clalms.

I claim:

1. In combination with a radiator and means for creating a blast of air therethrough, a set of horizontally disposed vanes pivotally sup-ported on horizontal axes adjacent said radiator, a set of vertical vanes supported vertically on said horizontal vanes, said su ports of the vertical vanes bein provided or by interfitting apertures and lugs formed in both sets of vanes.

2. In combination with a radiator and means for creating a blast of air therethrough' a set of horizontal vanes pivotally supported on horizontal axes adjacent the outlet side of said radiator, a set of vertical vanes notched to fit over the ends of said horizontal vanes, said vertical vanes also being rovided with lugs, and holes in some pf sai horizontal vanes for receiving said ugs.
